application filed April 25, 1902.

To all whom it may concern: I I

Be it known that we,'FRED A. ANDERSON and AARON A. BROWN, citizens of the United States, residing at Rawlins,-in the county of Carbon and State of Wyoming, have invented a new and usefulAutomatic Signal and Alarm, of which the following is a specification.

Our invention relates to certain improve-I ments in automatic signals and alarms, and has for its principal object to provide a suitable alarm for the protection of flocks or herds of cattle and the protection of growing crops from animals or birds.

A further object of the invention is to provide a device of this character in which the alarm will be of both a visual and an audible charactciyas more fully set forth hereinafter.

In the accompanying drawings, Figure 1 is a perspective view of an automatic signal and alarm constructed in accordance with' our invention, a portion of the outer casing being broken away in order to illustrate the interior construction. Fig.2 is a sectional elevation of the same. Fig. 3 is a sectional plan View of theapparatus on the line 3 3 of Fig. 2. Fig. 4 is a similar view taken in the plane through the lenses of the outer casing. Fig. 5 is a detail sectional View of a portion of the base of the structure. Fig. 6.is an elevation of that portion of the device shown in Fig. 5. Fig. 7 is adetail perspective View of one of the cartridgedischarging hammers detached.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of thedrawings. v

The base portion of the apparatus is in the form of a ring 10, having a plurality of supporting-legs 11, which maybe of any desired height in accordancelwith the elevation to be given the apparatus. In the baseis ar: rangedan annular series of openings 12-for the reception of cartridges 13, each opening being substantially in the; form of a gunbreech and suitablyrecessed .for the, reception of the rim of the shell. On the basering is removably mounted a ring 14, having depending lugs 15, fitting within the ring 10, said lugs having threaded openings for the reception of the inner ends of thumb-screws Serial N0.1O4,700. (No man.)

16, carried by the ring 10 and serving as a means of uniting the base and the upper portion of the apparatus. The thumb-screws may be readily loosened and the upper portion of the apparatus removed whenever it becomes necessary to place fresh cartridges .in position. The number of cartridge-receiving openings may be increased to any desired extent, in accordance with the number of discharges which are to occur during a predetermined period of time.

To the lower ring 14, the central opening of which is elliptical in form, for a purpose hereinafter described, there is secured a ring 18, having a series of openings equal in number to the nu mberof cartridge-receiving openings in the base-ring, and in the intermediate rin 14 a number of ta erin o enin s 19 are a b t! formed, one of such openings being arranged in alinement with each of the cartridge-receiving openings and the openings in the ring 18. In the openings of the ring 18 are secured the lower ends of vertically-disposed tubes 20, the upper endsof which are secured in similar openings in a top plate 21. Each ,of the tubes 20 is adapted for the reception .of a hammer 22, comprising an elongated cylindrical weight having a pointed lower end for operative contact with the head of the cartridge, and in the upper end of each hammer is formed an annular groove 23 for the reception of a spring-finger 24, the outer end of which is secured to the top plate 21, and

the inner end of which is free, said finger tending to assume a substantially radial position with respect to the center of the plate 21 and serving as a means for holding the hammer in an elevated position until such time as the spring is tripped and the hammer released to discharge the cartridge. For convenience in setting the hammers each of the tubes is slotted, as indicated at 25, for the reception of a the spring-finger to one side as the hammeris elevated, the stress of the spring causing it to return and move into locking position in the annular groove 23.

To the under side of the plate 21 is attached a clockwork mechanism 28, which maybe of any suitable character and provided with a propelling-spring to effect its operation for any desired length of time. The windingpost 29 of the clockwork extends up through a suitable opening in the top plate 21 for convenience in winding.

30 indicates an arbor driven by the clockwork and carrying a revoluble arm 31 at a point above the plate 21. This arm revolves at a predetermined speed, making, for instance, acomplete revolution in twelve hours and at the end of each hour engaging one of the spring-fingers 24 and eifecting the release of a cartridge discharging hammer. The number of cartridges and the intervals between firing may be altered in accordance with the conditions of use, and in some cases the intervals between firing may be unequal, so that at certain times during the night a discharge may be more frequently made.

Situated centrally of the tubes is a lamp 32, having an elliptical baseplate 33, which may be readily inserted through the previouslydescribed elliptical opening in the ring 14 and then turned until properly seated on top of the ring, thus ofi'ering a convenient means of removal when it becomes necessary to renew the supply of oil or clean the lamp.

To the lower end of the arbor 30 is secured a preferably metallic casing 34, having a series of openings which are covered by screens 35 of translucent material, which may be of the same color, but preferably of different color, in order that an observer at a distance may be informed that the signal is in proper working order between intervals of firing.

The device as a Whole is preferably surrounded by a protective casing comprising a cylindrical shell 40, having a closed top 41, provided with a carrying-handle 42. At the bottom of the casing are formed slots 43, having portions arranged in both horizontal and vertical plane adapted to engage the projecting ends of the thumb-screws 16, the whole forming a bayonet-joint, which may be readily engaged or disengaged when necessary. In the side of the casing are arranged lenses 45, one in alinement with each of the colored screens 35.

The operation of the device will be readily understood from the foregoing description. The cartridges are set in place, the hammers elevated and retained in position by the spring-fingers 24 until the latter are successively moved to disengaging position by the rotating arm 31, when the hammers fall and explode the cartridge. At the same time the revolving casing 34 will cause lights of different color to show successively through the various lenses, so that an observer at a distance may be informed that the apparatus is in proper working order.

Vhile the construction herein described and illustrated in the accompanying drawings is the preferred form of the device, it is obvious that various changes in the form, proportions, size, and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of our invention.

Having thus described our invention, what we claim is-v l.
